3,4-Dichloro-6-(trifluoromethyl)toluene

3,4-Dichloro-6-(trifluoromethyl)toluene can be used as organic synthesis intermediates and pharmaceutical intermediates, mainly used in laboratory research and development processes and chemical production processes.

500 ml of hydrogen fluoride, 600 ml of carbon tetrachloride and 140 g of 3,4-dichlorotoluene are reacted at 110?? to 115?? C. and 18.5 to 19.5 bar pressure. 151 g of a stubstance containing, in addition to 79.1% by weight of 3,4-dichlorotoluene, 20.2% by weight of 2-methyl-4,5-dichloro-benzotrifluoride, are obtained, corresponding to 74% of the theoretical yield, relative to 3,4-dichlorotoluene converted.
